For the walking-around photography I often do, I like 28-80mm or 35-70mm zoom lenses. They’re like having three or four prime lenses on hand, but without having to dismount one lens to mount another. Their maximum apertures aren’t as wide as the primes they replace — f/3.5 or f/4, rather than f/1.7 or f/1.4. Fortunately, I commonly shoot at f/8 to f/16 when I’m walking about in daylight, so that’s no big deal.
I’ve long wanted such a zoom lens for my manual-focus Pentax SLRs. I recently bought a 35-70mm f/4 SMC Pentax-A lens because I got a good one at a good price ($44 shipped) on eBay. I liked that it was a twist zoom rather than a pump zoom. I find twist zooms to handle a little more easily.
I took my Pentax ME SE and this lens along on a recent road trip up the Michigan Road to South Bend. Unfortunately, the lens made the ME SE front heavy, which detracted from this camera’s usual easy handling. I probably should have mounted it to my larger and heavier Pentax KM instead. But what was done was done, and I pressed on with a fresh roll of Fujicolor 200. Still, I always carried this kit in my hand, strap dangling. That tells me it wasn’t too heavy.
This lens suffers from a common malady among short-range zoom lenses: barrel distortion at the wide end. This photo shows it a little.
Fortunately, that’s easy enough to correct in Photoshop, which I did on all of the rest of the images so affected.
The lens doesn’t stay perfectly focused when you zoom. The amount of needed refocusing is tiny, however. You don’t need to correct it except when depth of field is shallow.
At 70mm, this lens focuses to four inches. What a nice touch. The lens focuses close at all focal lengths, but I didn’t check to see whether it’s consistently four inches, and I couldn’t find authoritative info on the Internet about it.
On this photo, the sun was off to my left and created a little flare. I suppose I could look for a hood to fit this lens’s 58mm filter threads.
I am satisfied with the lens’s sharpness.
The 35-70mm f/4 SMC Pentax-A is a solid, well-made lens. My copy is still well screwed together and tight. It handled and performed adequately.
This was the fourth roll of film I put through this Pentax ME SE, which I bought somewhat impulsively as I have a perfectly good regular Pentax ME. I’ll review the ME SE soon.
